Counseling from WTQL
counseling from wtql
Counseling from the Wisconsin Tobacco Quit Line (WTQL) consisted of 5 proactive calls to the participant to help them successfully quit tobacco use, plus ad hoc calls at the participant's initiation; also, WTQL coaches encouraged participants to see their health care provider to obtain Medicaid-approved smoking cessation medications to help them quit smoking.

financial incentive to participate
Participants in the Incentive condition received $30 per call for up to five WTQL calls taken; in addition, Incentive condition participants received $40 for producing biochemical evidence of abstinence at the 6-month follow-up visit. (Note that participants in both the Control condition and the Incentive condition received $40 for completing the baseline biochemical smoking status assessment visit and $40 for completing the 6-month follow-up biochemical smoking status assessment visit.) Compensation was in the form of prepaid Visa gift cards mailed approximately 2-4 weeks after the point of contact.

Description Previous research on providing incentives for healthy behaviors has shown that financial incentives can increase treatment participation and boost outcomes when they are tied to participation in evidence based treatments. However, most of this research has been done in laboratory settings and in relatively small clinical trials. This study is designed to test the hypotheses that incentives can increase both participation in smoking cessation treatment and resulting cessation rates, when they are offered to Wisconsin BadgerCare Plus (Medicaid) smokers as part of their health care. If successful, this treatment approach could be used more broadly to reduce the considerable financial and personal costs associated with smoking-related disease. In this study, Medicaid-eligible smokers were recruited from primary care clinics and from callers to the Wisconsin Tobacco Quit Line (WTQL) with randomization a Control condition and an Incentive condition. All participants were offered five cessation calls from the WTQL and participants were encouraged by WTQL coaches to obtain cessation medication from their primary care providers. All participants received payment for completing a baseline assessment ($40) and a 6-month smoking test ($40). Only Incentive condition participants received additional compensation for taking counseling calls ($30 per completed call) and for biochemically-verified abstinence at the 6-month visit ($40).
